I sent the cartridge with the suspected suspension problem to Peter at Soundsmith. I have verified no problems with turntable or tonearm by mounting different cartridges and they don't exhibit any problems. My original post was concerning antiskating and it's possible effect with this cartridges weird cantilever deflection when applying VTF.
Peter said that he can't duplicate the problem but it's definitely got one!
